To play Block Party, first, pick a card with a secret object on it. Then, grab some colorful wooden blocks and start building the object. Your goal is to have another player guess what you've built. When they do, both of you get points. Try to be the best builder in each round and complete the big challenge to earn a bonus point. Remember, the game is for 2 - 6 players and usually takes 15 - 20 minutes. It's for players aged 8 and above. After playing, keep the blocks in a dry place to prevent damage. Don't expose them to extreme temperatures or moisture. If the blocks get dirty, you can gently wipe them with a dry cloth.
